Backbone-Magnesium piece linking the upper cuff to the lower shell providing back support for better rebound coming out of the turn (rebound effect) & enabling a progressive but powerful forward flex

Ride & Hike technology-Salomon patented system combining the backbone release with a specific V-cut shape on the back of the lower shell. Allows wide rear cuff opening when hiking (Backbone unlocked) & true alpine forward flex when skiing down (Backbone locked) because the backside of the backbone fits precisely into the V-cut lower shell
